Researchers say they can't link depression to your genetic makeup, but the more bad things that happen to you, the more likely you are to suffer severe depression. Despite progress in risk gene identification for complex diseases, few disorders have proven as resistant to gene identification as psychiatric illnesses. Contrary to a previous report, an analysis of 14 previous studies finds no association between a serotonin transporter gene variation, stressful life events, and an increased...

Contrary to a previous report, an analysis of 14 previous studies does not find an association between a serotonin transporter gene variation, stressful life events, and an increased risk of major depression, according to an article in the June 17 issue of JAMA. The authors did find that the number of stressful life events is associated with depression.Despite progress in risk gene identification for several complex diseases, few disorders have proven as resistant to gene identification as...

The gene known as 5-HTTLPR plays a key role in determining how the neurotransmitter serotonin functions within the brain. Serotonin transmits chemical messages...
